On-site Activities
Schedule Activities Night 1 Wednesday (Sept 4)
Conduct IC rollers/GPS setup and trial runs (equipment vendors and FHWA IC team only) at the staging area. (3PM-5PM)
Conduct project briefing at the staging area and IC training for roller operators (7PM-8PM).
Start paving with one IC roller at breakdown and another IC roller at intermediate position.
Select a 500-ft section as a test strip to establish the rolling pattern. Conduct NG/GPS/LWD-a testing immediately behind the paver and at selected locations after each breakdown and intermediate roller pass within the test strip.
Perform production compaction using the rolling pattern. Conduct NG/GPS/LWD-a at selected locations after the finishing
rolling Night 2 Thursday (Sept 5)
Set up the GPS base station and IC roller/GPS system (by 7PM). Start paving with one IC roller at breakdown and another IC roller at
intermediate position. Conduct NG/GPS/LWD-a testing immediately behind the paver and at
selected locations after each breakdown roller pass within the 1500-ft section.
Conduct NG/GPS/LWD-a testing at selected locations after each intermediate roller pass within the 1500-ft section.
After the finishing rolling, mark 60 locations within the 1500-ft paved section. Conduct NG/GPS tests at marked locations. Conduct GPR within the test section. Conduct FWD and LWD-a tests at designated locations. Conduct coring at the marked locations.
Days 3 Friday (Sept 6 PM)
Conduct the Open House event including presentation and equipment demonstration.
GPS: A base station and a rover will be provided by Sitech West. NG: Nuclear density gauge and an operator will be provided by Teichert Construction. LWD-a: Lightweight deflectometer for asphalt tests will be provided by Kessler. FWD: Falling weight deflectometer tests conducted by Caltrans. GPR: Ground penetrating radar conducted by Caltrans research contractor. Coring: 60 X 4” cores will be taken by Teichert via a contract change order. Core tests: Bulk density testing of cores will be performed by Caltrans District 4 lab.
